Laparoscopic energy devices are essential tools in minimally invasive surgery, enabling precise cutting sealing and coagulation of tissue through small incisions in the abdomen. Despite their critical role, the ergonomic design of these devices has remained largely unchanged, continuing to follow a one- size-fits-all approach that does not reflect the diverse needs of surgeons and operating-room staff.

This project explores the impact of poor ergonomics on surgical performance and user wellbeing, with a particular focus on fatigue, musculoskeletal strain, and usability challenges experienced during procedures. Current devices often fail to accommodate variations in hand size, grip strength, and working style, contributing to physical discomfort and increased cognitive load, while also affecting workflow efficiency in the operating theatre.

Through a combination of research, user engagement, and iterative prototyping, this project identifies key barriers preventing ergonomic innovation, including regulatory constraints, sterilisation requirements, cost-driven procurement, and a clinical focus on device performance over user comfort.

In response, this project has developed an ergonomic energy device that reduces fatigue, improves usability, and supports a wider range of users, while remaining compatible with existing clinical practices. By integrating inclusive design principles, anthropometric data, and stakeholder input, the outcome seeks to enhance both surgeon wellbeing and overall surgical performance without compromising patient safety.
